The general object ofmy invention is to In rolls which are manufactured andtplaced provide an interchangeable journal with a on spinning machinery the predominating 'combinationof a screw' and a taper fit for structure has ajourn'al made integralrwith fluted textile rolls, which journal; may" be one roll which journal portion is squared and readily inserted into the extremity of the roll this squared portion is adapted to be fitted sections and -removed 'if--necessary,lit being into a square hole in the end of anotherrroll an object of my'inv'ention to provide a' very sectiomand as pointed out inmy objects of strong replacement part for'joining the secinvention it has'heretofore beennece'ssary in Se tions of rolls and one that'will not become replacing theworn outtportionlto sawofi the j driven in the end of the roll.

I this character or to neck from the roll and drill out the end of the roll and insert a new journal which is My invention can be applied to old rolls of new rolls, and in either described best by stating case my invention is 11 are first bored at the that the rolls 10 and end portions thereof by the cavity 12, and

then the smaller bore 10' tom of the bore 12, and then a reameris placed in the bore 12 which'reams out'the sloping shoulder portion 14 and then th i t r of the bore13 isth'feadedf V I then provide the journal portion or neck port on 15 which is adapted to fit into the bores 12 and 13, this journal portion 15 havingthesloping shoulderportion 16' and the threaded portion 17 on either end thereof. It is thus seen that the elongated portioniof the neck '15 which extends into the large bore 12 forms avery strong structure and this is necessary due tov the fact that between each of the fluted rolls as at the point 18 weights are place ,and this causes a good bitof strength to appear between the journal portion 15 in each of the rolls, but having the elongated bore" 12 into which thejournal or neck 15 fits without diminishing in size, I provide an additional reinforcement and a moresubstantial structure thanthat set forth in my Patent Number 1,659,261 ofeFebrua 'ry-l, 1928, which is similar touthe structure herein described withthe exception that the elongated'bore 12 is'notpresent,
